GEM SETTING Filed 001;. 15, 1951 'm n y v5 I!" I .I l X l l M Patented Nov. 1, 1932 UNITEDA STATES SVEN A. PILBLAD, or BoSToN,` MASSACHUSETTS GEM SETTING Application filed October 15, 1931. Sera1 No. 569,033.

My invention relates to gem settings for articles of jewelry such as rings, buttons and the like, and particularly to the means by which I am enabled to firmly secure in place either a single stone or more than one stone imposed one on another.

In the latter case it is thus possible to combine stones of different nature and color to secure an artistic effect, without cementing of the stones.

A common form of setting includes a box like socket in which a stone is placed and the upper edges of the sides rolled or staked to retain the stone in its setting.

In some cases a grille like cover, having a suitable device, is laid on the stone and the edges of the box sides rolled or staked to retain both the grille and the stone in place.

In my invention whi-le I use both a socket and a cover, my setting is completed without forming the edges of the socket toretain the stone or cover in place.

My invention consists in the novel means I employ to join my cover'and socket for use with either a single stone or more than one stone imposed, to secure the stone or stones in a firm setting. With my setting the cover member may be fretted to form an emblem or device exposing portions of the set stone, or may be formed to framev the stone or a pair of stones, one imposed on the other with the required device intaglio. In either case the essential features of my invention are retained.

vIn the accompanying specification and claims, and the drawing forming a part thereof, I have described-and illustrated preferred forms of my invention for use with both a single stone, or more than one stone in imposed formation.

I do not confine my invention to the particular forms illustrated and described, as modifications may be used within the scope 'of my claims.

In the drawing- Fig. 1 shows an enlarged section of a setting for ainger ring, in which my invention is embodied.

Fig. 2 shows a similar view with the elements in extended relation.

Fig. 3 is a plan view of a typical cover.

Fig. I is `an enlarged section similar to Fig. l in which a pair of stones are shown, one imposed on the other, and retained in setting by means of my invention.

Fig. 5 is a plan View of the same indicating the artistic possibilities.

Referring to the drawing, 10 is a fragment of a finger ring, having a flattened surface 11 on which is secured by sweating or other commonly'used means, the frame 12, which together with the surface 11 forms a socket in which a stone A may be placed. The frame l2 is provided on opposite sides with recesses 13, the axes of which are at an angle with the surface 11, opposite pairs con# vergent to intersect above said surface, as at 14, and each recess being slotted axially as at 15 to open on the inner walls 16 of the frame forming channels in respective faces of the Socket. y

The cover 17 in the form of a grille bearing av suitable device, is formed from thin metal, preferably with a border, although conditions inay besuch as to render this unnecessary. The cover 17 is of such size and form as to fit neatly within the socket and is provided on opposite sides with projections agreeing in position with -corresponding sockets 13, the neck 18 being adapted to extend through the corresponding slot 15 and the end 19 being formed to slidably fit the recess, and preferably being formed with a slight elevation above the upper surface as at 19. The projections are bent at a slight angle with the surface 20 which will form the inner side of the grille, and when applied With the stone in place, the ends 19 engage corresponding sockets, the inner surfaces 20 of the grille clearing the contiguous surface of the Stone.

By applying pressure to the upper surface 21 of the grille, the ends 19 ofthe extensions are forced into the sockets, which being angularly disposed relative to the inner walls of the frame, cause the extensions to bend o-n the line of junction with the grille, thus increasing the overall distance across opposite pairs of extensions to agree with the axial variation of the sockets. This in- 1 crease of length operates to firmly secure the ends in the sockets to prevent Withdrawal therefrom and removal of the grille. It will be obvious that the several elements of the frame and the grille Will be so proportioned that When the grille is pressed into place, the inner surface 20 of the grille will be approximately in complete Contact with the stone, and the upper surface of eXtension endsV will be substantially aligned With the upper edges of the frames, requiring. no finishing. Y

For eXtra safeguarding the upper edges of the sockets may be peened about the ends o f the extensions if desired.Y

In Figs. 1l and 5 the cover is formedV for settinga pair of stones A and A, thelatter being superimposed on the former, and an initial being shown intaglio both stones being exposed. This coveris securedin similar manner to form a secure setting for a pair of stones arranged as shown.

The advantages claimed for my invention includeY the setting of gems with greater facility; the combination of emblems in grille form with the stone used; the security of the setting and 'thecombination of a stone of one color or nature, imposed on one of diHerent color or nature, and secured in its setting by a fretted cover of artistic desie` VmHaving thus described my inventionj I claim:-

l. A gem setting comprising a stone or jeivel to be set; a box like socket to receive same, provided in opposite Walls with channels from respective inner'fayces, axially normal to the socket base and divergent 'from the open side of the socket toward the socket base ;l and a cover member having projections adapted to slidably engage the respective channels at their outlets and to be deflected under pressure applied normal to the socket base, to increase the over-all distance across opposite projections to retain engagement with the angular Walls of the respective channels and to resist separation therefrom.

2. A gem setting comprising a stone or jewel to be set; a box like socket to receive same, provided in opposite Walls with channels from respective inner faces axially normal to the socket base and divergentl from the open side of the socket tovvard the socket base; and a cover member having projections from opposite sides forming with the major surface thereof an angle With apex above said surface, and adapted to slidably engage the respective channels at their outlets and to be deflected under pressure applied normal to the socket base, tor increase the over-all distance across opposite projections to retain engagement Wit-h the angular Walls of the respective channels and to resist separation therefrom.

3. gem setting comprising a stone or jewel to be set; a box like socket to receive same, provided in opposite Walls With channels from respective inner faces axially normal :to the socket base and divergent from the open side of the socket toward the socket base; and constricted toward the respective inner faces of the socket; and a cover member having projections adapted to slidably engage the respective channels at their outlets and to be deflected under pressure applied normal to-.the socket base, to increase the over-all distance across opposite projections lo retain engagement with the angular Walls of the respective channels and to resist separation therefrom.

t. A gem setting comprising a stone or jewel to be set; a box like socket to receive same, provided in opposite Walls with reeesses, each connected by a constricted slot, with the respective inner face, the recesses being formed normal to the socket base and divergent from' the open side of the socket tov/ard the socket base; and a cover member having projections each approximating in contour the outlines of the respective recess and slot7 and adapted to slidably engage the respective channels at their outlets and to be deflect-ed under pressure applied normal to the socket base, to increase the 4overall distance across opposite projections to retain engagement with the angular Walls of the respective channels and to. resist separation therefrom.

5. A gem setting comprising a stone or jewel to be set; a box like socket to receive same, provided in opposite Walls with recesses, each connected by ay constricted slot, with the respective inner face, the recesses being formed normal to the socket base andl divergent from the open side of the socket toward the socket base; and a cover member having projections, each approximating lin contour the outlines of the respective recess and slot, and formed with an elevation, approximating the contour of the recess, the projections being` adapted to slidably engage the respective channels at their outlets and to be deected under pressure appliedL normal to the socket base, to increase the overall distance across opposite projections toretain engagement with the angular Walls of the respective channels and to resist separation therefrom.
